SPRING FOR CORSET-STIFFENERS ORSIIVIILAR ARTICLES.

SPECIFICATION forming part of Letters Patent No. 676,210, dated June 11, 1901.

` Application led January 15, 1901. Serial No. 435303. (No model.)

My invention relates to improvements in compound spirally-wound flat-wire springs in which two spirally-woundiiat-wire springs of known construction and composed eachof any suitable number of coils are connected together by placing them side by side with those edges facing each other where the loops formed by the coils are free and then winding or screwing through those loops a special binding-coil of exactly the same pitch as the loops, or, what will give the same result,4

pulling through those loops a binding-wire, like pulling the shoe-laces through the holes in the upper part of` lace-boots, and finally rolling or pressing the coils of the binding-wire fiat down upon or into the face of the wire springs. I thus obtain a compound spirallywound flat-wire spring which presents an almost-straight edge at both sides and which is strengthened in the middle part, and therefore is especially applicable for making stays or busks for corsets and bodices and for other purposes where great flexibility and a certain resistance against bending through in the middle are required.

On the accompanying drawings I show the new compound spirally wound flat wire spring by means of which I attain the objects in view.

Figure lshows part of the same, on an enlarged scale, with wire coils wound all in the same direction, the connectingwire being partly screwed in place and not yet pressed flat. Fig. 2 is a cross-section of Fig. l along line I I. Fig. 3 is a view of the same with the connecting-wire completely in place and pressed lat. Fig. 4 is a cross-section of Fig. 3 along line II II. Fig. 5 is a view of the new spring with wire coils wound in opposite directions, the connecting-wire screwed in place partly only. Fig. G is a cross-section of Fig. 5 along line III III.

Two, three, or more steel wires a and b are wound spirally around a mandrel of such thickness as will be prescribed by the width of the spring to be made. The spirals are then pushed oft the mandrel and pressed nearly fiat by the known process. Two such nearlyiiat pressed multiple-wire coils A and B are then placed side by side, with those edges facing each other where theloops C and D, respectively, are free. Both multiple coils are then bound together by pulling through the loops a binding-wire, like pulling shoe-laces through the eyes of lace-boots, or instead of such a plain binding-wire a binding-wire coil E may be used, the pitch of the coils of Awhich corresponds exactly to the distance of the loops O and D from each other in each mul- "tiple .wire coil A and B. This binding-wire is then screwed or wound into the loops C Vand D, passing alternately and regularly through the loops of the coil A and then through the adjacent loops of the coil B. This done, the whole fabric is pressed or rolled fiat, as `indicated in Figs. 3 and 4. By this both multiple coils A and B are rigidly bound together, so that the whole forms a strong but very iiexible steel spring. The central binding by the wire E forms, so to say, a sort of backbone of the compound spirally-wound Alat-wire spring.

It is not necessary that the coils A and B bewound both in the same direction. They may be wound in opposite directions upon the same mandrel or upon separate mandrels, but of same thickness, so that the pitch of the loops will be the same. A spring of this design is shown by Figs. 5 and 6. It will be seen that the coils d are wound in one direction, left to right, andthe coils Z9 in the opposite direct-ion. The pitch of thefree loops C D is, however, the same, and therefore the binding-coil E can be wound into these loops exactly in the same way as described in the preceding case, and the whole is then rolledor pressed dat and the fabric produced resembles the one described first in every respect, except that the coils in both halves are bent in opposite directions.

IOO

If desired,thin steel Wi res may be introduced into the loops C D or C' D and also into the little space left between the loops C and D or C' and D'-that is to say, between the binding-coil E or E', or only between the latter alone, or between the two first coils only, as indicated in dotted lines in they drawings. This would protect the main coils C D and C D' from being pushed toward each other if the binding by the coil E or E should happen not to be firm enough. This is, however, not essential.

` The essential feature of my present invention and the gist of the same is the binding of the two multiple coils together in the middle, whereby I obtain the strengthening central backbone and almost straight and closed edges 'at the two sides, which is not found in similar fabrics of known construction.

What I therefore claim as myinvention is- As an article of manufacture a spring for corset-stiieners and similar articles consisting of two multiple wire coils each composed of several concentric wires these two multiple coils being bound together by an intel'- vening wire which passes through the loops of the two coils alternately, the whole being flattened as set forth.

' In testimony whereof I have affixed my signature in presence of two witnesses.
